Poly(4-Vinylpyridine) (P₄VPy): A Basic Catalyst for Facile Synthesis of Biscoumarin and Dihydropyrano[3,2-c]Chromene Derivatives in Aqueous Media

Abstract

An effective method for the one-pot synthesis of dihydropyrano[3,2-c]chromene and biscoumarin derivatives have been reported using poly (4-vinylpyridine) as a cheap, efficient and recyclable catalyst. All reactions are performed in a green media during acceptable reaction times with good to high yields.
